PDRN, or polydeoxyribonucleotide, is emerging as a key skincare ingredient for 2026, according to dermatologists and beauty experts. Often derived from purified salmon DNA, it is already popular in medical aesthetics and K-beauty, and is now appearing in high-street products.
Dr Ewa Kania, an aesthetic doctor, explains that PDRN is a DNA-fragment-derived regenerative ingredient originally used for wound healing. In skincare, it signals fibroblasts to support collagen and elastin synthesis, enhance barrier repair, improve hydration, and reduce inflammation. Consultant Dermatologist Dr Aiza Jamil adds that PDRN has long been used clinically and is now formulated into serums, creams, ampoules, and toners.
Unlike traditional actives that exfoliate, PDRN supports the skin's own repair systems. Benefits include improved barrier strength, enhanced hydration and plumpness, calmer skin, and gradual improvements in elasticity and texture. Dr Ross Perry of Cosmedics Skin Clinics describes it as a long-game ingredient that encourages efficient self-repair without dramatic overnight changes.
On TikTok, the #PDRN hashtag has over 180,000 posts, and searches for K-beauty on TikTok Shop have risen 125% in the latter half of 2025. Grace Vernon, Head of Boots Ignite, confirms PDRN is a top trend for 2026, noting that while injectable treatments are popular, topical products offer a more accessible and less painful alternative.
